FLOOR 0R ROOF CONSTRUCTION FOR COLD-STORAGE 0R OTHER BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 572,259, dated December 1, 1896. Application filed March 19 1896. Serial No. 583,860. (No model.)

To all whom it may concern.-

Be it known that I, IRvIN G. HooPER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Floor or Roof Constructions for Cold-Storage or other Buildings; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art ,to which it appertains to make -and use the same, reference being had to the accompanying drawings, and to letters of lreference marked thereon, which form a part of this specification. v

This invention has reference to a novel arrangement and construction of the roofs and floors of buildings, such as in cold-storage houses, breweries, and the like; and the invention has for its obj ect to provide a iiooring or roof construction for cold-storage buildings and the like having a perfectly-insulated air-space, which prevents the cold air within the building from becoming contaminated with the warmer atmosphere on the outside of the building, it being a well-known fact that the air will find its way through the brick or stone walls and the flooring or roofing unless properly insulated.

The invention therefore consists in the novel construction of a floor or roof embodying the principles of my present invention, and which will be hereinafter fully set forth, and valso in the minor arrangements and combinations of the parts to be fully brought out in the accompanying specification, and finally embodied in the clauses of the claim.

With these several ends in view the invention is illustrated in the accompanying drawings, in which- Figure l is a cross-section of a portion of a floor orr roof made in conformity with my invention, and Fig. 2 is a similar view of a portion of a roof or fioor of a modified form of construction. Fig. 3 is a sectional View of a portion of a floor or roof of still another slightly-modified form of construction, and Fig. 4. is a similar view of an asphalt floor made according to the provisions of my invention. Fig. 5 is another sectional View of a portion of a floor or'roof of still another modified form of construction.

Similar letters of reference are employed in all the above-'described views to indicate like parts.

In the several views of the drawings, in which I have represented in section portions lof a roof or iioor to be used in cold-storage houses and the like, a a are the usual forms of iron girders or other like beams, having their ends set in the walls of the building in the usual manner. a' of said beams I start the usualvform of brick arching l), which is constructed in the well-known manner to produce an efficient construction which will thoroughly resist fire and exclude air-drafts from the portions where the arches are joined to the iron beams. Extending along the entire length of the web of said beams d, at about the middle thereof, are secured by means of suitable rivets d2 the anglevirons d3, as clearly represented in Fig. l. Upon said angle-irons a3 I build up a second brick arch, b', similar to the arch b, of sufficient thickness, so that its upper arched surface and the lower arched surface of the arch h' will form a suitable air-space cbetween therespective arches and the iron beams d for supporting the floor or roof.

As will be seen from an inspection of Fig.r

l, the upper curved surface of thelower arch b has been insulated, first, with a layer of `tar-paper d and then with a coating of pitch d of proper thickness,while the upper curvedv surface of the upper arch b is similarly insulated with a layer of tarepaper d2 and a coating of pitch d3 of the proper thickness,thereby producing a thoroughly-insulated air-space between the two arches b and b', and a floor or roof will be the result which isa non-conductor of either heat or cold, causing the retention of the cold air Within the building and preventing the warm er air from striking through said arches. Upon the upper portions of said iron beams a a are laid the wooden cross-beams c, and upon this the wooden Hoor-boards e', then a layer of tarpaper f, a second layer of tar-paper f', and upon this is arranged a layer f2 of asphalt, concrete, or other like material.

From an inspection of Fig. 2 it will be seen that the layer of tar-paper f and the asphalt or other like layer f2 may be dispensed with using simply the two layers of floor-boards e On the lower flanges a TOO and e2,with the tar-paper f between them. In said Fig. 2 I have also illustrated the iron girders vor beams c a, provided with a centrally-arranged ilange a4, which is formed integral with the web of the beam, thereby dispensing with the use of the rivets CL2 and the time and labor in securing the angle-irons a3 to the web of the girders. The upper arch b is started on these projections or iianges a4, as clearly represented in said Fig. 2, and in all other respects the arrangement and construction of the several parts are similar to that illustrated in said Fig. l.

In Fig. 3 Ihave illustrated a modified form of construction embodying the principles of my invention, in which the arches b b are started directly upon the upper surfaces a5' of the girders a ct and the wooden cross-beams e are laid directly upon orin the arches b' b', substantially as shown. When the invention is to be used in connection with lioors other than wood floors,`there is placed upon the upper surface of the arches b a heavy layer of `concrete g, which may be finished off'in` the usual manner, or may have a finish g of asphalt,` as illustrated in Fig. 4.

To prevent any air from getting between the web'of the girders a and the end courses of the upper arches b/ in case of a faulty construction, I can cover the upper portion of the girder a with a suitable cover 71 of wood or other material, in such a manner to leave an empty space around said upper portion of the girder, and through a hole h in said cover I pour hot pitch, which will entirely cover the upper part of the girder a and hence form an air-tight joint at the point where the arch b joins the web of the girder.

From the above description it will be seen that I have devised a simple construction for the floors and roofs of cold-storage buildings, breweries, and the like, provided with welllinsulated air-spaces, which will prevent the cold air in one room from being contaminated with the warmer air in another room or from the outside atmosphere.

Of course it will be evident that changes may be made in the details of the arrangements and combinations of the parts which go to make up the floor or roof, and hence I do not limit my invention to the exact arrangements and combinations of the parts as herein set forth; as, for instan ce, in place of the tarpaper and pitch employed, I may use any other suitable non-conductor of heat, as asbestos, &c., or, in place of the iron girders a, I may use other like beams or longitudinal courses of brick.

Having thus described my invention, what I claim is I l. In a building, the herein-described floor or roof construction, comprising therein, in combination, girders, as a, or the like, arches of brick, stone-or the like, supported thereon, formed with an air-space between said arches, and an insulatingmaterial on said arches, consisting of -a layer of tar-paper and a layer of pitch, substantially as and for thefpurposes set forth.
